. 4 Claims. o1-4 29o) This invention relates to strainers, and par ticularly to the type of strainer adapted to receive Waste material.

The strainer differs from form incorporates a strainer wherein and whereby liquids may be maintained'therein or permitted to be discharged therefrom and through the base thereof.

The arrangement is such that the particular strainer is dripless when the base is closed against passage therethrough of liquid.

To accomplish this dripless feature,

I have provided a novel arrangement of parts, members and features, which render the said strainer economical of manufacture, superior to ordinary types of strainers, durable, and generally superior.

. The present invention likewise incorporates means whereby the base of the strainer may be maintained elevated above a supporting mem-' her, to the end that liquids may readily drain therefrom.

With the above mentioned and other objects in view, the invention consists in the novel and useful provision, formation, construction, association, and relative arrangement of parts, members, and features, all as shown in a certain embodiment in the accompanying drawing, described generally, and more particularly pointed out in the claims.

In the drawing:

Figure l is a side elevation of the improved strainer,

Figure 2 is a bottom plan view of the strainer,

Figure 3 is a sectional view on the Figure 2,

Figure 4 is a sectional view on the Figure 2, and,

line 33 of line 4-4 of Figure 5 is a sectional view on the line 5-5 of Figure 2.

These side walls may be straight sided and substantially at right angles to the base, or inclined at an angle other than 90 to the base. In the present instance, the said side walls are sloped slightly outwardly, as best shown in Figure 1 and, in addition, the side walls along the rim portion, as shown at 1.

struction adds to the appearance of the container and likewise adds to its durability.

The base 6 of the container is sloped downwardly toward what may be termed the center of said base, as shown at 8. The base, however, is '5 not curved but resembles a hollow cone with a slightly sloping side wall, An inverted apex is provided, formed by striking the material of the base inwardly at 9. The said base is provided with a plurality of spaced transverse perforations I'D, through which perforations liquid would ordinarily readily pass. 'Within the objects of the present invention, I do not desire that liquid should at all timesreadily pass through the perforations of the base, and therefore I have provideda disc 'H for the purpose of closing vthe'perforationsof the base when the disc is moved in one direction. This disc is adapted to conform shape to the base and therefore the disc is bent in such a manner as to best fit upon 0 the base. This said disc'is provided with a plurality of transverseperforations i2 having substantiallythe same identical arrangement as the perforations Hlof the base 6. This disc is provided-with an annular flange l3. Carried on the surface of the disc and bounded by said annular flange is means I4, constituting a packing. This packing may be formed of graphite composition, and the said packing has perforations extending therethrough in conformity to the placement of the perforations l2 in the disc II. A pin I5 is adapted to secure the disc and its associated packing with the apex of the base 6 of the container and in such a manner as to permit a turning movement of the disc and packing relative to the base. The said disc is provided with integrally formed leg members I6. In the present instance, three of said equidistantly spaced legs are provided. The purpose of the legs is to provide means whereby the disc may be rotated, as well as a means whereby the base of the device may be held elevated above the surface of a supporting object.

For convenience, I have provided two spaced stops l1 and I8 between which one of the legs may be moved to position the perforations of the disc and its packing in alignment with the perforations in the base of the container, and in a second position to move said perforations out of alignment. These said stops are conveniently provided by upsetting the metal of the base, as best shown in Figure 3.

In operation, reference is had to Figure 1. It may be assumed that the strainer disc has been rotated against one of the stops to close the said perforations of said disc relative to the perfora tions of the base 6. Liquids will not then pass through the perforations, due to the fact that the perforations in the base are covered over by the packing. When the disc is rotated by positioning one of the legs adjacent the other stop, perforations of both the disc and packing and the base are in alignment and liquid may pass therethrough. The legs on the disc permit the container to be maintained above a supporting object so that the container does not rest in a pool of discharged liquid. The arrangement of the base is such that liquids are readily discharged from the container without there being pockets for the collection of grease and the like. Furthermore, it is intended that the perforations should not be of a size suflicient to allow large particles to pass therethrough.

The device does not necessarily have to be used for receiving waste products but may be used for holding fruit and the like which is to be washed.

When the strainer as an entirety is being supported above an object, it is apparent that the user may grasp one of the legs and rotate the container to discharge liquid and without the necessity of having to lift the container, or in any wise touch it, in order to determine the position of the strainer disc relative to the bottom of the container.

It is obvious that various changes and modifications and variations may be made in practicing the invention in departure from the particular showing of the drawing without departing from the true spirit of the invention.

I claim:

1. A strainer of the character disclosed including a container, the base of which is provided with transverse perforations, a disc rotatively secured to the base and provided with perforations adapted to align with the perforations of the base when the disc is in one position and to be out of alignment with said perforations of the base when the disc is rotated to a second position, said disc being formed with spaced legs for supporting the said container above an object, and whereby when the perforations of the disc and the container are in alignment, any liquid within the container may drain therefrom.

2. In a strainer of the character disclosed, a container having the usual side wall and a base tapering downwardly from said side wall toward the center, said base being provided at a zone thereof with transverse perforations, a disc rotatively secured to said base and conforming in shape to the slope of the base, and a packing secured to the disc and interposed between the disc and said base, both said packing and said disc being provided with perforations adapted to align with the perforations of the base when the said disc and packing are in one position.

3. In a strainer of the character disclosed, a container having the usual side wall and a base tapering downwardly from said side wall toward the center, said base being provided at a zone thereof with transverse perforations, a disc rotatively secured to said base and conforming in shape to the slope of the base, packing secured to the disc and interposed between the disc and said base, both said packing and said disc being provided with perforations adapted to align with the perforations of the base when the said disc and packing are in one position, and leg members forming extensions of said disc for elevating said container above a supporting object and whereby liquids may readily drain from said container when the perforations are in alignment.

4. A strainer of the character disclosed, including a container, the base of which is provided with transverse perforations, a disc rotatively secured to the base and provided with perforations adapted to align with the perforations in the base when the disc is in one position and to be out of alignment with said perforations of the base when the disc is rotated to a second position, and supporting means for elevating the container above a supporting object whereby liquids may readily drain from said container when the perforations are in alignment.
